Abstract
A lock includes a pair of spaced apart parallel bolts connected by a plate extending between the bolts. A slot, formed in a hinged structure, such as a gate, extends from a free edge of the structure (an edge opposite a hinged edge) to an end point at a determined distance from the free edge. The plate is received in the slot. Each bolt is located on an opposite side of the hinged structure, when the plate is received in the slot. The slot defines a range of sliding motion of the plate and bolts.
Claims20
A locking mechanism for a hinged wing, the locking mechanism comprising:
- a pair of bolts including a first bolt and a second bolt, the first bolt being spaced apart from and parallel to the second bolt, the first bolt including a first end, a second end opposite the first end and a first length from the first end to the second end of the first bolt, the second bolt including a first end, a second end opposite the first end and a second length from the first end to the second end of the second bolt;
- a plate extending between the pair of bolts, the plate having a top, a bottom, a first side, a second side, a leading edge and a trailing edge, the first side of the plate being fixedly attached to the first bolt, the second side of the plate being fixedly attached to the second bolt, the leading edge being a determined distance from the first end of the first bolt, and the leading edge being the determined distance from the first end of the second bolt, and the plate having a thickness and a width, the width being a distance from the leading edge to the trailing edge, and the width being greater than the thickness of the plate and less than the first length of the first bolt and less than the second length of the second bolt.
A locking mechanism for a hinged gate, the hinged gate having a free end, and a fence post being adjacent to the free end, the locking mechanism comprising:
- a slot through the gate, the slot extending horizontally a determined distance from the free end of the gate, the slot having a first end at the free end of the gate, and a second end opposite the free end of the gate;
- a pair of bolts, the pair of bolts including a first bolt and a second bolt, the first bolt being spaced apart from and parallel to the second bolt, the first bolt including a first end, a second end opposite the first end and a first length from the first end to the second end of the first bolt, the second bolt including a first end, a second end opposite the first end and a second length from the first end to the second end of the second bolt;
- a plate assembly extending between the pair of bolts, the plate assembly including a female plate with a plate channel attached to the first bolt, and a male plate attached to the second bolt, the male plate being at least partially received in the plate channel of the female plate, and the female plate having a thickness;
- each of the first bolt and the second bolt having a bolt diameter, and the bolt diameter being greater than the thickness of the female plate;
- and
- the plate assembly being received in the slot, the plate assembly being movable from the first end of the slot to the second end of the slot, and the first bolt and second bolt being in a locked position when the plate assembly is adjacent to the first end of the slot, and the first and second bolt being in an unlocked position when the plate assembly is adjacent to the second end of the slot.
